1. The independent research and development of lifting system and positioning system, ensured the accuracy and repeatedly of the testing process.
2. Coating adopted car paint technology with white color. Looking more decent, and with the advantage of fullness, high gloss and more scratch resistance. Used for many years looking still bright as new.
3. The optical system designed by senior optical engineer can meet the definition of hardness testing requirements of our customers.
4. Testing method, testing power and duration time can be displayed directly on the LCD screen. The hardness value can be displayed directly by entering the indentation diagonal length and avoid the complication of the look-up table.
5. According to different visual habits of the operators,the strength of the light source can be adjusted. To avoid the visual fatigue for long time operation.
6. The testing data able to be printed directly by the built-in printer.
7. Can be connected with computer, used the image analysis software to analyzing the physical and chemical properties of the material.
8. Ferrous metals, non-ferrous metals, castings and alloy materials.
9. Structure of metal, metal surface processing layer, plating layer, hardening layer ( oxidation, coating and a variety of infiltration layer )
10. Heat treatment and carbonation specimen, quenching and mini parts which with miscellaneous point.
11. Applicable to the Knoop hardness test of glass, ceramic, agate, precious stones and other non-metallic hard but brittle materials.
